Well, I'm happy to report I think I solved the oopses, thanks to Phillip Reisner's clue. Now just still lost with the SLOW SLOW initial synchronisation between devices. My solution against the OOPS was: 1) configure the kernels (exact same version) without SMP 2) compile each kernel on its own system 3) THEN, compile drbd modules again for that kernel I take this was a mismatch between kernel and system, or between kernel and the drbd module, or possibly, my setup didn't like SMP kernels as much. But with regards to the SLOW initializing/synching problem, see below, I still have no clue or fix. A benchmark was attached previously, dma is on and all, I'm happy for any clues on known drbd issues or (non-lethal!) hdparm commands... version: 0.7.6 (api:77/proto:74) SVN Revision: 1663 build by root at primary, 2005-01-24 11:08:48 0: cs:SyncTarget st:Secondary/Secondary ld:Inconsistent ns:0 nr:15936 dw:15936 dr:0 al:0 bm:130 lo:0 pe:0 ua:0 ap:0 [>...................] sync'ed: 0.1% (122282/122298)M finish: 108:41:45 speed: 284 (240) K/sec 1: cs:SyncTarget st:Secondary/Secondary ld:Inconsistent ns:0 nr:15720 dw:15720 dr:0 al:0 bm:128 lo:0 pe:0 ua:0 ap:0 [>...................] sync'ed: 0.1% (120009/120024)M finish: 106:40:30 speed: 244 (240) K/sec version: 0.7.6 (api:77/proto:74) SVN Revision: 1663 build by root at secondary, 2005-01-24 11:08:24 0: cs:SyncSource st:Secondary/Secondary ld:Consistent ns:16368 nr:0 dw:0 dr:16368 al:0 bm:3 lo:0 pe:0 ua:0 ap:0 [>...................] sync'ed: 0.1% (122282/122298)M finish: 139:07:49 speed: 240 (240) K/sec 1: cs:SyncSource st:Secondary/Secondary ld:Consistent ns:16152 nr:0 dw:0 dr:16176 al:0 bm:1 lo:0 pe:0 ua:6 ap:0 [>...................] sync'ed: 0.1% (120008/120024)M finish: 102:24:27 speed: 272 (240) K/sec /dev/hda: Timing buffered disk reads: 8 MB in 3.07 seconds = 2.60 MB/sec /dev/hda: Timing buffer-cache reads: 492 MB in 2.01 seconds = 245.18 MB/sec
